Since there is no abstract available, we provide the first paragraph  

Large-scale studies provide strong evidence that high-volume hospitals or high-volume surgeons improve short-term outcomes of patients undergoing high-risk surgical resection for solid cancers [1]. Although high-quality evidence for the role of surgical resection quality is lacking, there is some data supporting the view that surgeon's experience influences also long-term survival of patients with resectable gastrointestinal tumors including esophagus and gastric cancer [2, 3]. In a recent issue of the World Journal of Surgery Sundelöf et al [4] report on the impact of hospital or surgeon volume on both short-term and long-term outcomes of patients with esophageal and esophago-gastric junctional (EGJ) cancer. In an absence of randomized trials and limitations of this study [4], we would like to comment particularly on surgeon's volume on long-term outcomes of patients with gastro-esophageal cancer.
